Rear Sway Bar

Been tinkering with the idea of installing a rear sway bar on the D40.Being that mine is not a dirt dwellor but a blacktop toy am wondering what others think.
Hellwig in the US makes a kit for the truck and I can get 1 for around the $500 mark. Alot of coin so want to make sure its going to be a worthwhile add on

It may improve understeer. Give it a go I reckon.

I actually have my understeer well under control. I adjusted my camber to almost zero and the horrid understeer vanished. Oh did I mention I also installed lighter springs so the front dips under breaking so I go neg camber lol.
Its just a lot of coin for possibly not much difference.

Stiffening up the rear will definitely change the turn in. My guess would be added understeer but it may give you oversteer, being a ute, a suspension specialist would know better.

Yeah I was thinking I really should get decent rear springs first.
The rear breaks loose too easy now so even stiffer rear could be even worse .

AFAIK, You don't want the camber changing under braking as it can cause bump steer.

Dion will know much more than me.

Tell me more about how you use your vehicle? I know it's a safety car or something at track days?

Your dampers take care of the fast response body roll - long sweeping high speed bends are where an ARB would help you out. Do you take on many of those? Usually with utes the issue is rear wheel jacking leading to oversteer, since the rear suspension is ridiculously stiff when unloaded and the front is much softer.

other than my normal daily I also use it as a Chase/Fire/Rescue vehicle on racetracks. It means driving as hard as possible chasing cars around the track on first laps.
The biggest issue I had with the truck was the massive amounts of understeer. The front end would chatter at speed. Since installing the new UCA and coilovers it now no long understeers at all. Well not as far as a "truck" would go.
Under normal driving the front springs keep the front up no dramas. Its only under very heavy braking (140kmph into a 60kmph turn) that the front will dive.
Bear in mind I drive a 4x2 so a lot lighter in front anyway

Well unless you're suffering from too much oversteer, I'd leave it as is. If you are feeling like there's too much oversteer, soften the rear springs and dampers and restore the roll resistance with a rear ARB.

for high speed driving i would look at fitting a panhard rod. leaf springs do a fairly crap job of locating the rear axle.

Yeah all good advice guys. Think Ill give that a miss and for the money I could be half way to a decent rear end with coilovers .
Something like this

or even


Grand plan would be to use the exisiting front spring mount as the front pivot point.
Just an idea !!!!!!!
